Setting the Date and Time

Setting the Date and Time Using an NTP Server

To obtain the date and time from an NTP server, perform the following steps:

Detailed Steps

clock summer-time

zone

date

{day month | month

day} year hh:mm {day

month | month day} year

hh:mm [offset]

Example:

hostname(config)# clock

summer-time PDT 1 April

2010 2:00 60

Sets the start and end dates for daylight saving time as a specific date in a specific year.
If you use this command, you need to reset the dates every year.

The zone value specifies the time zone as a string, for example, PDT for Pacific
Daylight Time.

The day value sets the day of the month, from 1 to 31. You can enter the day and month
as April 1 or as 1 April, for example, depending on your standard date format.

The month value sets the month as a string. You can enter the day and month as April
1
or as 1 April, depending on your standard date format.

The year value sets the year using four digits, for example, 2004. The year range is
1993 to 2035.

The hh:mm value sets the hour and minutes in 24-hour time.

The offset value sets the number of minutes to change the time for daylight saving
time. By default, the value is 60 minutes.

clock summer-time

zone

recurring

[week weekday

month hh:mm week weekday

month hh:mm] [offset]

Example:

hostname(config)# clock

summer-time PDT

recurring first Monday

April 2:00 60

Specifies the start and end dates for daylight saving time, in the form of a day and time
of the month, and not a specific date in a year.

This command enables you to set a recurring date range that you do not need to change
yearly.

The zone value specifies the time zone as a string, for example, PDT for Pacific
Daylight Time.

The week value specifies the week of the month as an integer between 1 and 4 or as
the words first or last. For example, if the day might fall in the partial fifth week, then
specify last.

The weekday value specifies the day of the week: Monday, Tuesday, Wednesday, and
so on.

The month value sets the month as a string.

The hh:mm value sets the hour and minutes in 24-hour time.

The offset value sets the number of minutes to change the time for daylight savings
time. By default, the value is 60 minutes.
